I need to amend a 2018 tax return online. I tried the instructions found in another post, but that only lets you download the .tax file and the turbotax client and then expects you to edit it in the client. Problem with that is that I already have the client installed and when I try to open the .tax file it wants me to buy the additional states I need for $44.99 which I think I already paid for last year online.
I need to know how to amend this 2018 return online or locally without having to rebuy the states needed.
Thanks.
