Premium tax credit with nondependent child on marketplace policy for part of the year

For 2021, I had my nondependent 23 year old child on my marketplace policy for the first four months of the year.  I removed her from my marketplace policy at the end of April, at which time she commenced coverage on a  non-marketplace policy, with no advance credit payments, that she obtained directly from a private insurer.  I have read the instructions for Form 8962 and cannot figure out how to (or whether I need to) do any allocation for the first four months of the year.  The instructions, and various examples provided within, do not appear to address this circumstance.
