I paid 2020 fed taxes. I got notice to pay penalty & inter. of 30.08. I amended after efiling (no change to tax amt) Do I ignore, can't get a live person?

IRS phone ctr constantly says Due to High Volume, please call back later due to COVID19.  Their system confirmed they got my tax pymt on 4/26/21.
The notice gives IRS, Fresno, CA 93888 address.  
Do I send letter with ACH #'s (proof from bank for 2020 pymt) to Fresno address, that will take 30 days or more for them to get to?  I can't fill out 911 form for Taxpayer Assistance unless it's been more than 30 days and I haven't heard from IRS.  Please help!
