1) The IRS has advised to NOT amend returns for the UCE (Unemployment Compensation Exemption).  They have not (to my knowledge) address the APTC issue.

2) The IRS has to revamp the Form 8962 to deal with ARPA.  Once the IRS does so, then the software companies can move forward.  Their hands are tied until the IRS takes action, then it will take time to rewrite the software AND then get IRS approval.   

Don't expect it next week.....
