Why am I asked to pay when I have a simple return of just SS Income, no tax or deductions or credits

It says fees will be determined 'at time of filing' well, NO, you determine my fees now, thank you. I was charged last year for free filing and had to contest it. TT is not honest. And this year they said we're sending you a link for the free file and they never did. Same as last year, apologized for the charge but then never refunded me.
