If you use TurboTax Download, you may have more capital gains to report than there is space provided on the S3 tax form. If that's the case, you'll need to include any additional capital gain amounts on the S3-Supplementary Statement form.
Note: This is only available using the Forms method in TurboTax.
To access this form
If you're in EasyStep mode, go to Forms view by selecting Forms from the menu.
Select View from the toolbar, then select Find Form. The Form Lookup box opens.
Under Keyword to search for, enter S3.
Select the S3-Supp form, then select OK. The Schedule 3 - Supplemental Statement opens.
Enter the remainder of your capital gains.
