PA does not have legal separation so client has to file MFS (no dependents). In 2019 she took ACA with PTC. MFS are not allowed the PTC, except under 2 exceptions, neither of which she qualifies for. However, ATX is allowing the credit on 8962. There is a box on the top of the 8962 to check if taxpayer meets the MFS exception. It does not matter if I check the box or not, ATX is giving her the credit. I have deleted the form and reentered it, still same result. Don't know how to fix this.
