John,
Thank you for that, but, it does not resolve the known problem that TurboTax and Coinbase are not cooperating anymore on CSV files for some reason.
I tried reformatting the columns from the Coinbase CSV file to what TT seems to ask for. I have copied in an extract of 5 rows, plus the header row, and TT still gives me an error. Does anyone have a sample CSV file that TT will accept for cryptocurrency tax filings?
My extract below shows two coins that I was given 'rewards' for by Coinbase, and I have not sold them, but, according to the IRS rules, I have gained income, hence the 'proceeds' shown. What is that TT needs to see in order to import a CSV with ~200 entries?
