@sclocke6 -  I am shooting darts here, but just some thoughts: 

while you paid the $14, 165 (and I am assuming that is the total for the year), did you pay 1/4 of it no later than the due dates of June 15, Sept 15, Jan 15 and April 15?  

Look at the math on Form 2210 and see whether your 2020 tax was pulled correctly onto Line 8.

Look at form 2210 Underpayment Worksheet, it will show how the $43 was calculated.  Can you see what happened?  

Yes, I now see where that $43 was coming from.  I had to go into the "open forms" to see the actual 2210 (it's not in the list of forms otherwise).   That showed me in detail how everything was calculated.

Thanks!

if you look at the actual instructions for the 2210 certain taxes and certain credits are not includable on lines 1, 2, 3  (current year)  and 8 (prior year)

Yep..... that's where I messed up.
