Found that importing transactions seems to be the best for my situation. Sharing in case it helps someone else having issues.
1. Auto Import from Coinbase - shows $10k+ in transactions when mine were less than <$1k
2. TurboTax Gain/Loss CSV from Coinbase - transactions with cost basis values less that <.005 caused 0.00 value errors that needed to be reviewed...this was more than 300 transactions for me (tiny ALGO rewards).
3. Transaction CSV - imported successfully and appears to have calculated correctly.
Intuit, I hope you can get these issues resolved, and I sure hope you are handling these imports correctly. A little concerned since I got different numbers with each import.
Per Expert @Jamesg, here's steps for uploading a CSV:
Go to Federal / Wages & Income / Your income / Investments and Savings.
The .csv should follow this format.
