Can not connect USAA to Qbooks 2021 Desktop OLSU-1011 error

Glad to have you here in the Community, @Jonquilia.

The error OLSU-1011 usually occur if: 

• The Financial Institution Directory (FIDIR) is not updated to include information for your financial institution.
• There's possible damage to your company data file.
• You're in Register or Classic mode instead of Side-by-Side or Express mode.

We can check the default account for your personal and company preferences.

Here's how: 

1. Log in to the company file as Admin, and then switch to single-user mode.
2. Go to the Edit menu, and then click Preferences.
3. Select Checking, and then click the My Preferences tab.
4. Under Select default accounts to use, put a checkmark of all of the checkboxes.
5. Click the Company Preferences tab. 
6. Under Select default accounts to use, put a checkmark for the two options.
7. Click OK.  

Once done, set up the account again for online banking.
