In addition to the info provided above by stinkerbellkity, if you haven't actually physically printed and mailed them, you can still switch the filing method and efile, if you wish.
If you DID print and mail them, however, then do NOT efile a second return.
So if you haven't filed, here's how to open an unfiled return to change the filing method to efile:
- Log into your account, and at the Tax Home or in the section "Your Tax Returns & Documents" for 2019, look for a link "Add a State."
- Click on "Add a State." (That doesn't really add one; that's just to open the return.)
- Once the return is open, go through the REVIEW section to be sure everything is still in order.
- Then go to the FILE section and change the filing method to efile.
- Then continue on answering all the remaining screens and at the final step click a big orange button "Transmit Returns Now."
