I made an installment with $XYZ (all the tax I owed) on Apr 17. On the same day, I submitted my tax return in which I listed this payment. On May 19, IRS requested that I pay $XYZ...(I am 100% sure it's because they did not see my installment payment via PayUSATax) ...
Should I submitted the payment again by the deadline and argue later or should I not pay....Thanks!!
