I downloaded the CSV from Coinbase, deleted the top 7 rows (email etc), but get an error when I upload "No headers found in this file". There are headers so how to fix?

Turbotax says "Your Coinbase file will be compatible as long as it's under 2251 transactions." My transactions are less than 300. I deleted the top 7 rows that had a disclaimer, my email, etc. I also tried bolding the headers but still doesn't work.
