Thanks for getting back into this thread, @Electricpreacher.

I'll assist you in fixing the printing issues of your sales statements to the Windows envelope in QuickBooks Online (QBO).

First off, are you using the Intuit Window Envelopes, or is it from another brand? If it's from another brand, the addresses may not align with the envelopes properly since it will depend on the size you bought to make it fit properly, among other factors.

Otherwise, if you're using Intuit window envelopes, you'll want to ensure your form templates are customized correctly to align them. Here's how:

1. Go to the Gear icon, then select Custom Form Styles.
2. Choose a form, then tap Edit.
   
3. Pick the Design tab.
4. Select Edit Print Settings. 
5. Place a checkmark on the Fit to window envelope checkbox.
6. Tap Done to proceed.
   

On the other hand, you'll want to follow how QBO formats your return address if you're having an issue with it. Refer to this article for details: Print forms for window envelopes in QuickBooks Online.
