How do I find the submission ID (20 characters) of my accepted federal return?

If you are trying to find out if your return was accepted,  you will see the status of your return in Tax Home after signing into your TurboTax Online account. For more information, please see How do I check my e-file status?

I am trying to find the "submission ID" that was submitted with my electronic return. It doesn't appear anywhere in my e-file status.
