I just amended my 2016 and 2017 returns and dont know what forms I have to send in

I don't know what forms to send in for amended taxes 

After you file

Did you use the 2016 and 2017 desktop software to do so?

After you file

Yse, and a lady at turbo tax walked me thru it. For 2016 there were 2 different forms, 5 pages total. For 2017 there was just one form, 3 total pages. I think the form changed from one year, but not certain.

After you file

Click on FILE then PRINT then save the return and read the filing instructions ... you need to send forms that explain and support the column B entries.
