How to apply 2016 payments to 2017 tax
Last year after filing my 2016 tax and receiving a refund, I realized a need to amend which will result in additional taxes. I paid the estimated additional taxes but got a CPA to file the amendment, during which I forgo to ask the CPA to apply the prepaid estimated tax.
I'd like to not amend the 2016 return again, and instead apply the payment to my 2017 tax bill. Is it feasible and how do I go about it?
