What documents do I mail for Form 8453 with box checked for Form 8949?

Hello, in 2024 I had short-term and long-term cost basis that weren't reported to the IRS on my Form 1099-B for Charles Schwab.  Additionally, I sold a rental property and wasn't issued a 1099-S since the sale price was under $500,000.

TurboTax is saying I need to print Form 8453 and attach Form 8949 or an acceptable continuation sheet for Schedule D. 

Do I include my 1099-B statement showing the cost basis not reported to the IRS?  For the rental property, do I include the escrow settlement statement and any supporting documents/calculations that went into calculating the realized gains?

Many thanks!

Yes, you will want to include a copy of you 1099-B with the 8453.  You do not have to include the escrow or other documents related to the sale of the rental property- the IRS is looking for the itemized line items if you used a summary for the stock sales.  

See E-file.

Thank you for the response.  That makes sense since I used the summary feature to report the gains/losses of my stock sales. It's only 3-4 stocks that had value of less than $1,000 so should be easy to itemized.

The Form 8949 also list out my sale of the rental property.  So I do not need to provide additional documents since it's technically itemized when I entered the sale of the property correct?  Thanks.

No, you don't need to document the rental property sale unless TurboTax instructed you to do so.

Thank you! That makes sense. The instructions only popped up when I was entering the summarized gains/losses for sale of stocks that wasn't reported to the IRS.
