"Check This Entry" 'Schedule of gain and losses: Date sold must be entered.' I have many sold dates. None of them are working. What should I do?

I see that you're in the Online Premiere software.  That's the right product for what you want to do.

There's a specific area to enter Cryptocurrency.

1. Federal
2. Wages & Income
3. Investments and Savings
4. Stocks, Cryptocurrency, Mutual Funds, Bonds, Other (1099-B)

If you've started this section you will see a bar for "Crypto (1099-B)"

If you click REVIEW you will come to Review your none sales

You will be able to consistently enter the dates.
