ACA & 1095-C

My daughter changed job in September, 2021.  Her new employer didn't offer her health insurance until November, 2021.  Meanwhile, we covered her with our ACA policy from September to December without realizing her employer's insurance offer in November.  We paid 100% for the ACA allocation. 

 

My questions are:  Do I need to reduce the ACA premium credit for Nov and Dec?  If so, how do I go about doing it (i.e. what forms and where to remove her portion of the ACA subsidies)? 

 

(Note:  My daughter received a 1095-C from her new employer notifying IRS that she was offered insurance for Nov and Dec).
