I don't see one of my state tax returns that I need to print and mail in. I only see the Turbo Tax cover sheet

It says: Your District of Columbia state tax return (Form D-40B) shows no balance due or refund amount and Your tax return The official return for mailing is included in this printout. Remember to sign and date the return. Attach copies of all W-2s and 1099s to your return, however there is no form attached and I have to mail in this form.
