As long as you haven't submitted your tax return for e-filing, you can log back in to your account to edit.
Sign back in to your account and from your Tax Home screen, you can choose a particular section to revisit for editing. There's also a Search bar at the top of your return you can use to search and "jump to" a form or section of your tax return. I've attached a screenshot for reference.
Is their any type of way to edit my tax return if I e-filed it already?
Yes you have to file an amended return.
You cannot change or add anything on the return that you e-filed. It is too late, just like when you put an envelope in a US mailbox
Now you have to wait until the IRS either rejects or accepts your return. Which won't be until Feb 12 this year. If your return is rejected, you will be able to go into your account and add or change it and resend it. Click on Add a State to let you back into your return..
If the IRS accepts your return, then you have to wait until it has been fully processed and you have received your refund or paid the tax due. THEN you can prepare an amended tax return 1040X and mail it in. You cannot e-file an amended return. Meanwhile, DO NOT change anything on your return until you start the amended return. If you did change or add the missing info then take it out and put your return back to the way it was when you first filed it.
