Long Term Care expenses and reimbursments

What should I do if Long Term Care costs paid in 2019, were reimbursed by the LTC Insurance Company in the early January 2020?   I feel these reimbursements should be recognized on the 2019 tax return, so they off set the payments made by my Mother-in-Law to her LTC facility in 2019.  Am I thinking correctly?  If I don't use them to offset her 2019 payments made, she will end up being taxed on money she should not be taxed on.

This is the second Time I have posted.  Could some one please give me their help?

Thanks,
