Sorry--you cannot attach stuff to an e-filed return.   If the IRS wants more information from you they will request it be sending you a letter.

Thanks. If I enter the amount from this 1099-K on TurboTax, it will automatically be counted as income, correct? However, being an inheritance, it is not taxable by the IRS. How do I deduct it?

Please clarify your question.

 

  • Who issued the 1099-K?
  • Who was the recipient?
  • Is it in your name?
  • Did these transactions happen after the decedents passing?

Please contact us again to provide some additional details.

The 1099-K was issued in my name by the auction company that sold a painting left me by my late father. It was sold 3 years after his death.

I suppose I could print out my return and mail it,  along with the supporting documentation. It would be nice if there were an easier way, however.

I agree, but there is a reason that we don't provide a vehicle for attaching forms.

 

  • The E-Filed tax returns are essentially just used as electronically processed with little human intervention.
  • The attached forms will probably be ignored.
  • If you mail the return it is manually converted to data and the attachment would be identified.
  • The system could be upgraded, but that is what we have now,

It would be wise to mail it.
