How can I find out if I filed my 1096 for 2021?

Do you really mean 1096?

Form 1096 is used to transmit paper Forms 1097, 1098, 1099, 3921, 3922, 5498, and W-2G to the IRS. 

Yes

If you filed using TurboTax Quick Employer Forms, see the message at the Home Page.

TurboTax Quick Employer Forms Common Questions may be found here.

I e-filed my form(s), how will I know it was accepted with the IRS or SSA?

After e-filing your W-2 or 1099 form, please monitor your filing status on the Quick Employer Forms Home Page. The e-file status will update from "Sent" to "Accepted" or "Rejected" when the Government Agency processes the form. The status change may take up to 2 to 4 weeks. You will also receive a notification by e-mail when the status changes. For W-2 and 1099-NEC, e-file is due by January 31, 2023 . For 1099-MISC, 1099-INT and 1099-DIV, efile is due by March 31, 2023 .
