Schedule D: Line 16 does not include capital asset sales because you have exceeded the maximum number of sales supported for individual reporting.

TurboTax is equipped to handle around 10,000 individual transactions per brokerage account.

 

If you hit the transaction import limit, you can enter a summary for each sales category.

Your brokerage statements should include a summary of your transactions, grouped by sales category, for example, Box A short-term covered or Box D long-term covered.
