I efiled the return but I a Certificate of Rent Paid, and it said I would not be able to efile if I have this CRP? How do I claim for the CRP now

You have to print and mail the M1PR:

Form M1PR is filed separately from your Minnesota State Tax Return and isn't due until the August 15th. You may file Form M1PR and claim a refund for up to one year after the original due date. If you file later, you won’t receive a refund.  Refer to the steps below: https://ttlc.intuit.com/replies/5787924
