How long does Turbo Tax save an in-progress tax return? I started my 2021 return and had to stop and now it seems to be gone. Where can I find it?

I finished 80% of my return last year but had to stop for various personal reasons. I planned on completing now as I do my 2022 return, but the 2021 return is not showing up in My Returns. Does TurboTax delete after a certain amount of time?
