Sure thing, let us know here or there (both?) if any workarounds help you.
I myself will likely do the suggestion where you pull the data (provided via "magic" api call to fetch your investing data) out of the filing and then re-enter manually as a lump sum P/L which doesn't require any dates.
Just procrastinating actually trying that cause I'm frustrated as hell with TurboTax rn, I doubt the issue is on the end of several different investing brokerages' API's (I was a Stash customer in 2020, aka Apex Clearinghouse Corporation is my brokerage where I fetch data from).
Plus this api fetch worked 100% perfectly last year. Granted I had a lot more activity this year, but none of it was any new "kinds" of activity, so I don't understand why it's any more complex to handle this year than last year. I suspect the TurboTax development team(s) introduced a software bug this year that causes this issue.
