Retirement tax questions

This method does not work. TurboTax won’t let me get past entering something called “number of days in the long term care period” and “costs”  when you get to the part that checks the federal return for errors, TurboTax shows it’s an error not to input these numbers. Form requires them, I guess. TurboTax  is failing here— WHAT IS A LONG TERM CARE PERIOD? 

I got 100% reimbursed in 2022 by my LTC insurance company. I should not have to input anything about LTC periods.
