limits to Rollover from a traditional IRA

I clawed back my MRD for 2020 (except for paid taxes)  from my traditional IRA and later attempted a Roth rollover of 5 figure sum. The turbo tax interview  brings penalty warning exceeding $7,000. Is there a work around and response I'm not seeing. It should be unlimited rollover from my IRA to the Roth IRA. How do I proceed?
