Since your return has already been filed and accepted by the
IRS, the only way you can change it to file with your most recent 1099 is to amend
the return.
Before doing so, you should verify whether the 1099 you received is a corrected 1099 or an additional one.
If it is a corrected 1099, be sure to compare it to the previous 1099 to see what has changed.
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. You have
plenty of time to do this, so there is no rush.
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.
