I recently completed my 2020 taxes and sent them by mail. I had a balance due that I was going to pay when the deadline was near. I went back into turbo tax and ran an update and due to the unemployment credit my taxes are almost half. Can I just send a check now with the original voucher for the new, correct, amount and let the IRS Sort it out or should I send an amended return along with the check that will include a new voucher and amount due. As of 4/27/21 my taxes show non file with the IRS so they have not yet been processed and accepted.
