After you file

Excuse my very vague question. Here is a little more detail. 

I was on unemployment in 2020 and sometimes they took taxes out some times they didn’t (the system is awful). However I filed in February and received my refund and since the new law was past after March and I filed, I was told the federal would automatically be changed if needed. I amended my state as per requested to by the state, by now I’m wondering if I should of amended the federal as well. 

thank you!
