Hi there, @OhioGuns.
Thank you for reaching out to the QuickBooks Community. I understand how important it is to have all your financial accounts linked and working correctly in QuickBooks Online. It sounds like you're having trouble linking your credit card account with Pedfed.org while other accounts link without issues. Let's walk through some steps to resolve this.
Since you have already tried linking your PenFed Credit Union Savings account, let's ensure that bank allows credit card accounts to connect through QuickBooks Online. When you connect your financial institution to QBO, our system will automatically detects your bank accounts. Please contact PenFed Credit Union to ensure there are no restrictions or issues on their end that might be preventing the connection.
After that, you can try linking your credit card account again. If the problem persists despite verifying with your bank, I recommend contacting our QuickBooks Online support to have this investigated.
Moreover, you can also manually upload your transactions into your QuickBooks Online account.
If you have any further questions or need additional assistance, please don’t hesitate to reach out again. We're here to help ensure your QuickBooks Online banking connections are smooth and effective!
