If I filed my tax return before 10,200 tax credit was law, will my return be processed as normal with the tax credit refund coming in May?

Or will I have to wait until mail and get it all as one refund?

The IRS will adjust your refund based on the unemployment deduction in May. You don’t have to do anything.

The answer to your question is not clear from the IRS postings.  As indicated, generally do not need to amend for Federal.

However, taxpayers would have to file an amended return if they did not originally claim the EITC or other credits, but now are eligible because the [unemployment comp] exclusion changed their income.  These taxpayers may want to review their state tax returns as well.
