I need to know where i can get the function back to write checks not pay online?

Thank you for taking the time to post in the QuickBooks Community, marie.

If I understand correctly, you're creating a bill and want to write a check instead of paying online. I'm here to help you with this.

QuickBooks Online (QBO) provides the Save and schedule payment as the default option after entering the necessary fields in your bill sheet. To change it to a regular check, you can choose Save and close. Please refer to the image below.

Alternatively, we can directly write a check to pay your open bills.

1. Click on the + New button in the Navigation Bar.
2. Select Check under the "Vendors" heading in the drop-down menu.
3. Choose the bill you've created from the Add to Check sidebar and click Add.
4. Select Print check, or Save and close to save and print the check later.

After this, I'm adding this article as a reference in checking your print alignment before printing checks in QBO: Print a check in QuickBooks Online.

Let me know if you have further updates or concerns about creating checks in QBO. Take care.
