I've tried SO MANY times to get to the screen to be able to amend my 2020 return following directions and clearing out my cache. It doesn't want to work.

I have to amend my 2020 taxes because I did not  use my husband's disability status to avoid the 10% early withdrawal penalty when he got lump sum payments  from his pension and 401k. He did use the CARES Act Covid-19  $100,000 exemption.

I don't know why when I go to the part that says amend 2020 return, 2020 flashes on the left side of the screen and then signs me out.
