I would like to take a deeper look at this. However, I need a diagnostic file which is a copy of your tax return that has all of your personal information removed. You can send one to us by following the directions below:

TurboTax Online:

Sign into your online account.
Locate the Tax Tools on the left-hand side of the screen.
A drop-down will appear. Select Tools
On the pop-up screen, click on “Share my file with agent.”
This will generate a message that a diagnostic file gets sanitized and transmitted to us.
Please provide the Token Number that was generated in the response.

TurboTax Desktop/Download Versions:

Open your return.
Click the Online tab in the black bar across the top of TurboTax and select “Send Tax File to Agent” *
This will generate a message that a diagnostic copy will be created. Click on OK and the tax file will be sanitized and transmitted to us.
Please provide the Token Number (including the dash) that was generated in the response.

*(If using a MAC, go to the menu at the top of the screen, select Help, then, “Send Tax File to Agent”)

It is line 28 and it is not picking up int, div and capital gains included in agi from federal return

Your federal AGI only includes $6 in interest. $31,339 was not included in your federal AGI. Of the amount not included in Federal AGI, $16,762 was added back to Michigan AGI. There is a worksheet in the Instructions for Schedule 1 that shows how the amount on Line 28 is calculated. It is on page 17 of the link above.

The maximum deduction on Line 28 is $28,548 less the amount of your Retirement & Pension Subtraction on Schedule 1, Line 27, which is $15,681. $28,548 - $15,681 = $12,867 << That is your maximum deduction allowed on Line 28 of Schedule 1.
