Remember, IRS told us NOT to amend for the UI exclusion, they will do that on their end. So you should wait for that to happen, then youd use the IRS corrected figures in the Original Column of the 1040X....if tax credits are involved this could become tricky and may require the use of overrides to get you to the proper "original as corrected by IRS" figures, since PS will make these changes automatically as well.
