Retirement tax questions

Thank you so much for this.  I did my Roth on 12/31/20 and then realized with all the 1099's and a K1 and a bonus I was over too.  Until I saw this, after reading the IRS code like 10x and still not completely sure, I was going to have to go to a CPA for this one thing.  TY so much for posting this.  This was all that was holding me back from filing.  I only needed the first section, as going forward my income has increased enough that all my IRA contributions will be Traditional Non-deductible again.
