After you file

Yes but be careful!

 

If you want to see your actual entries you can go back through it again but be careful not to change anything or you will overwrite and lose your real return.  In fact if you go back through some sections they will reset to the default answers and you need to answer them again.

 

Click on Add a State to let you back into your return.

From Tax Home (the first screen you see after you sign in), scroll down to Your tax returns & documents. You may have to select Show to open the drop down.

 

Select 2021, and then select Add a State (you're not actually adding a state, this is just the workaround).
