Stuck in the same situation, although I don't think it hung up on the summary transactions in my case, but instead on the miscellaneous income from staking rewards. Now I'm locked out of any access to continue with the return. Don't want to go through the tech support song and dance to try to get an escalation. Anyone successfully use the download version instead to complete their taxes? I started looking at H&R but their import system is terrible and 8949 data has to be manually entered, which is horrible even in summary form.
