Thanks both! A follow up question is:
On my latest tax return 1040 form, it says I owed IRS 5k. I made online payment for $7k using debit card because initially I got wrong tax due amount due to various reasons.
Now if I mail my return to IRS without attaching any online payment confirmation doc, would IRS know that I owed them 5k but paid 7k, and eventually returned me $2k?
Thanks!
