Oh, wow! I did not know this. I electronically filed my taxes in March, and it said I owed $4500. I was going to wait to send a check on the tax deadline; however, about 2 weeks later on 4/3/2023, I received another charitable giving summary statement that I forgot about and amended my tax return to add it. The amount was enough to lower my tax bracket to get a refund of $121. Since I corrected everything before the deadline, I thought the IRS would accept the correct tax return. It doesn't seem logical to bill me, especially after they accept the amended tax return.
