Update, I tried removing my crypto transactions and seeing if it would at least let me review/print right before it efiles and this time it worked. So it seems I was right, due to the large amount of data (3000+ transactions) TurboTax can't handle it because as soon as I added it back I get the same errors. This leads me to believe this is the reason for the Transmission error.
Common Turbo tax!
Btw, just found this after my troubleshooting. Calling them now in hopes to find a solution, maybe desktop will work for my situation but what's odd is they say the Desktop app supports 2000 transactions which if true will still be the same issue then? Guess I'll find out soon!
