I forgot to include a 1099 in my return. What should I do?

[AnnetteB · Accepted solution]

If your return has already been filed and accepted by the IRS, the only way you can change it to include your 1099 is to amend the return. 

At the current time, the amended return Form 1040X has not been released by the IRS for filing.  After it has been released, TurboTax will provide instructions for how to amend your 2018 return. 

See the information below for further information about amending your return using TurboTax.  The article will be updated with more details after the amendment form is released by the IRS.
