Also I have tried different versions of CSV as well as changed the headers, nothing is working

We've built a solution that allows you to import transactions from Coinbase to TurboTax, with plenty of help and resources along the way.

 CSV files will include the cost basis of your Coinbase transactions (if available) so TurboTax Premier can easily help you file your cryptocurrency transactions.

See if this Turbo Tax FAQ helps, How do I get a CSV file from Coinbase?

Coinbase ended up completely removing this CSV report which contains the gains/losses calculated. I ended up going with a 3rd party tool and it worked seamlessly - https://cryptotrader.tax/blog/how-to-file-your-cryptocurrency-taxes-with-turbotax

it seems turbo taxes solution to this issue is I pay another company $50  to get a report to file my taxes

I finally figured out the correct CSV format from Robinhood ... which was providing txt files instead of csv files (no surprise there, right?)

Try using these headers and column formats.  Hopefully it will work for anyone struggling with this.
