I don't recall entering estimated tax payments before submitting my return. Does the automatically credit those payments, or do I need to file an amendment?

IRS should catch this for you, as the payments are a credit on your account.

You cannot file an Amended return anyway until the ordinal is processed, so watch for the refund, and if it did not take the estimated taxes paid into account then file an Amended return.

However I do not think you will have to.
