Received an interest payment notice (form CP22A) from IRS due to filing a revised 1040X
It arrived with a payment coupon and I sent it in, including a personal check, via regular postal mail.
Now, 2 weeks later, the check still has not cleared so I suspect it's lost in the mail.
Since I have an EFTPS
There is a selection for 'Audit Adjustment' and under it 'Interest Payment' and I simply enter the tax year. There is no way to identify the form CP22A but my soc sec is the logon and I've used it to make 1040ES payments already
I understand it's possible the lost check will turn out later but it would be better that I've paid the interest twice than not at all.
