Investors & landlords

Accurately reporting PTP/MLP income and transactions in TurboTax involves several steps:

Step 1: Gather your tax documents:

• Form 1099-B: Reports the sale of stocks, bonds, mutual funds, and other securities.
• Schedule K-1 from the PTP/MLP.
• Supplemental information provided by the PTP/MLP detailing income recapture (included with K-1).

Step 2: Entering Schedule K-1 Information
TurboTax Online:

• Log in and open or continue your return.
• Go to K-1.
• On the Schedules K-1 or Q page, select Yes.
• On the Did you receive any Schedules K-1? page, select Yes.
• Select Start next to the type of Schedule K-1 form you have (Form 1065 for partnerships), and enter/review your information.

TurboTax Desktop:

• Open TurboTax and continue your return.
• Select Search Topics. Search for and select K-1.
• On the Schedules K-1 and Schedule Q screen, select Yes.
• Select Start next to the type of Schedule K-1 form you have (Form 1065 for partnerships), and enter/review your information.

Enter PTP/MLP Details:

• Confirm/Enter the partnership's Employer Identification Number (EIN) and other relevant information as shown on your Schedule K-1
• Check the box for “This partnership ended in 20XX.”
• Choose “Complete disposition” or "Disposed of a portion..."
• Choose “Sold Partnership Interest.”
• Enter original purchase and sale dates.
• Enter Sales information from Schedule K-1 Supplemental Information.
  Note: Since you received a 1099-B for this transaction, it's important to make sure $0 of Capital Gain is reported on the K-1, as follows:
  • Sale Price = zero
  • Partnership Basis = amount of ordinary gain from Supplemental Info multiplied by -1 (ie: reverse the sign).
  • AMT Basis = amount of ordinary gain for AMT from Supplemental Info multiplied by -1 (ie: reverse the sign).
  • Ordinary Gain = gain/loss per Supplemental Info.
• On the screen "Review Investment Gain or Loss on Sale," verify that this screen reports all zeroes. This is the expected outcome if your entries are correct.

Input Income and Deductions:

• Enter amounts from each box on your Schedule K-1.
  • Box 1: Ordinary business income/loss.
  • Box 20 (Code 2): Section 199A information.
  • Box 20 (Code AB): Section 751 gain/loss
  • Passive Loss Carryovers as negative numbers (regular, AMT, QBI).

Step 3: Entering Form 1099-B:

• Navigate to the 1099-B section:
  • TurboTax Online/Mobile: Go to 1099-B.
  • TurboTax Desktop: Search for 1099-B and select the Jump to link.
• Follow the onscreen instructions. When you reach "Let's import your tax info," choose how you want to enter your 1099-B:
  • To import your form: Select your brokerage or financial institution from the list. Enter your sign-in credentials for your account, then select "Get my form."
  • To enter your 1099-B manually (recommended): Select "Enter a different way," then select your investment type on the next screen.
• On the following screens, answer the questions about your 1099-B. When you reach the "Review your sales" screen, the form you just imported should be listed.
  • Otherwise, to add another 1099-B, select "Add investments." 
  • Select "Continue."
• Enter the details from your Form 1099-B (separate long-term and short-term):
  • Note: If the K-1 Supplemental Information has separate long-term and short-term sales, allocate the 1099-B information between the two, using the percentages provided on the K-1 Supplemental Info.
  • Long-term/Short-term basis not reported.
  • What investment did you sell [Stock (non-employee)]
  • Description: "Sale of [PTP/MLP Name] Units."
  • Date acquired & sold.
  • Proceeds from sale: (portion for this section, if allocating).
  • Cost basis:
    From K-1 Supplemental Info: Original Cost plus/minus Cumulative basis adjustments plus/minus Ordinary Gain/Loss from Section 751.
  • Example:
    • Original Cost = $100,000
    • Cumulative adjustment to basis = ($20,000)
    • Ordinary Gain = 15,000
    • Adjusted Cost Basis to enter = 100,000 - 20,000 + 15,000 = $95,000
  • No special situations.
  • Result should equal Capital Gain/Loss from K-1 Supplemental Info.
  • Add another sale for short-term, if allocating

TurboTax will report the capital gain or loss on Schedule D (Part I - Short-term; Part II Long-term) and ordinary income on Form 4797 Part II Line 10.
