I e-filed my federal tax return but on Filing Instruction sheet it said to mail in form 8453 along with form 8949. Wasn't form 8949 part of the e-file? When I printed out my return 8949 was included. The email I received from TurboTax verifing that my tax return was acepted noted: You're officially finished filing your federal taxes.
To me that means I don't need to send in 8949. In my 16+ years of using TurboTax I have never had to do this.
If you entered summary transactions of your capital gains and losses, you may have to mail in Form 8453 and Form 8949.
In general, you are supposed to list each stock transaction line by line on Form 8949. You can aggregate transactions for which:
If you do not have any summary transactions, or if all of your summary transactions meet the rules above, you don't need to mail in anything.
If you have at least one summary transaction that does not meet the requirements above, go ahead and mail in the paperwork as TurboTax is instructing.
