Glad to see your first post in the Community. I'd be happy to share with you the steps to connect your Etsy account to QuickBooks Self-Employed (QBSE) through the banking page.
Here's how:
Go to the Gear icon, then select Bank accounts.
In the search box, enter Etsy.
Select Continue. If you've already connected a bank account before, select Connect another account.
I'm also sharing this link for your future reference. You can use this when selecting the right category based on the Schedule C and expense categories.
I'm always around if you have an additional concern about anything else in QuickBooks. Take care!
