QB changed three of my invoices from Overdue to Deposited. No deposits have been made and I did not change the status. How do I prevent this from happening.

Good Afternoon, @magreillyus. 

I'm here to help you solve the question about your invoices saying deposited when there hasn't been any made in QuickBooks. To make sure I give you the best solution to your issue, do you use our Payments (Merchant Services) feature, and did your customer pay the invoice directly?

If so, then follow the steps below to ensure the deposit was made through the Merchant Services Center. 

1. Sign in to the Merchant Services Center. 
2. Select Activity Reports. 
3. Pick Transactions. 

If not, you can find the deposit that was made by checking the Audit Log. Here's how: 

1. Go to the Gear icon in the top right-hand corner. 
2. Under the "Tools" section, pick Audit Log. 
3. Use the fields on the Filter panel to choose the appropriate User, Date, or Events filter to narrow the results.
4. Tap Apply. 

If you're still not able to locate the transaction, then I recommend contacting our Customer Support Team. They have additional tools to look further into your account. 

I want to make sure that you're able to get this resolved as soon as possible. Let me know if this helps. Have a wonderful day!
