Finally got it to work thanks to the suggestions. Here's a couple details on my situation, and what fixed it.
I had a total of 3300+ transactions across many different platforms.
KuCoin 2500
Robinhood 570
Coinbase 84
Coinbase Pro 15
Gate.io 8
Kraken 48
etc.
Solution:
All I did was delete the Robinhood income, and used the "try a different way" followed by "type it in myself" function. I entered the Cost, Proceeds, and Robinhood account number, then was prompted to upload a required 1099 PDF provided by Robinhood. This brought the Robinhood transactions from 570 to 1. Tried filing again, and it worked.
I may have gotten lucky that, that was the only one I had to do that with. Not sure if it worked for me because it reduced my transactions to a number that TurboTax could handle, or if it had anything to do with Robinhood. Either way, hope this helps as it helped me.
