As long as you have not yet actually filed (i.e., not yet efiled
or actually mailed the return), you can make changes.
If TurboTax thinks you are finished you have to open your return
back up.

Log in and go to your 2018 Tax Timeline.
·
If TurboTax thinks you are finished, there will be no "Take
me to my return" (continue return) button.
·
So in that case then scroll down to Add a
State." (you don't really add one; that's just to get the return
to open up.)
·
Once the return is open, you can make whatever changes you need
to before filing.As long as you have not yet actually filed (i.e., not yet
efiled or actually mailed the return), you can make changes.
NOTE: Do NOT use this method to open a return to
make changes to an already-filed return (one that has actually been mailed or
efiled.) If you
later need to make changes to an already-filed return, you have to go through
the formal amending process, and your return must start off exactly as
originally filed.
