Bank acct has updating up to date & none to review, but the QBO and Bank don't match. Bank stmt has 6 old transactions that failed to upload. How best to post now?

Hi there, 

Welcome back to the Community. I'll be happy to share info so you can get back on track with doing what you love. 

You're more than welcome to post the transactions as bank account activity. Doing this will affect the QBO balance. You can also use journal entries to fix the balance. 

There's a great article from our Community which I recommend you to check out using this link here. The article has more info on how to fix beginning balance issues in QuickBooks. I suggest reaching out to your accountant for advice on how to handle the 6 transactions. 

In the meantime, feel free to ask other questions. I'm here to help.
