Retirement tax questions

Ahh mea culpa.  When I checked the Form 5329, I apparently had input by mistake that this excess Roth IRA payment was for prior year excess contribution of $6000, not for 2020 tax year.  So when I went back in TT, I changed that and now I owe no additional $360.  Have to admit the prompts from TT on when you contributed Roth IRA and excess Roth IRA for 2020 or previous are confusing.  Thanks for your help!!!
