After you file

Nope.  I just tried to reinstall state program for 2020 after reinstalling Fed program from disk (back when they sold disks).  I could not download state (even though I paid for it) and have since received advice from community that this is no longer feasible. 

 

I'm still within the statute of limits for amending my 2020 state return and I can no longer use the software used to prepare it.  The only advice I get is to prepare a manual amended return which is frankly ridiculous for a complicated return.  This is why I purchased the software in the first place.
