I can share some information about how address labels work, TTahbo.

Unfortunately, we're unable to change the preset labels in QuickBooks Desktop. Additionally, Avery #5160 is currently unavailable in the program.

You'll want to select Avery #5260 instead. This label format is exactly the same as Avery #5160 in size (1" x 2-5/8") and available in similar materials (matte white and clear film). Here's how:

1. Select File from the top menu bar.
2. Choose Print Forms.
3. Select Labels, then enter the name of your customers or vendors.
4. Click Print, then go to the Options tab.
5. From the Label Format drop-down menu, choose Avery #5260.
6. Click Print to complete the process.

I'll be right here to keep helping if you have further questions. Assistance is just a comment away.
