Do you mean a Form 1099-DIV, or Form 1099-INT? We ask, simply because a "1099-INV" does not exist. However, the answer to that really doesn't matter, as you are now in possession of a tax document that you didn't include on your original tax return. That's what's really relevant.
When you receive tax
information that is different than the information you used to file
your original tax return, and that new information contains any kind of income not previously reported, then
you will want to change your original tax return to reflect the new data. That process is called "amending" a tax return. If you
filed a state tax return too, you would need to amend that as well as your federal tax return.
But before you begin with an amended
tax return, please know that you'll need to first wait until your original
return is processed, and your original tax refund is sent to you. After
that time you can then print and mail in your amended return (plus state, if
applicable). And yes, amended tax returns must be printed on paper and
physically mailed; they cannot be e-filed.
For further information on amending,
please find below a link to a TurboTax webpage for the current year amendment
process. We keep that page updated throughout the tax filing season, and you will find information there on the necessary mechanical processes required in TurboTax.
