Retirement Savings Contribution Credit for a Former Student

I graduated from college May 6, 2023.  I am a *former* student.  I started a full time job soon thereafter, and contributed to a retirement plan.  No one can claim me as a dependent because I supported myself for more than half the year.  I haven't been a full time student for 9 months now.  I will not be a full time student ever again.  Must I designate myself as a full time student for Tax Year 2023?  I lose the Retirement Savings Contribution Credit if I do!  This seems to violate the spirit of the law IMHO.  Thank you.
