Hi there dijoyes64,
It’s important that all your transactions are entered correctly so that your books are balanced. QuickBooks Online is a tool that can connect to various services from apps to import information. I can point you in the right direction for help with your Square transactions.
In order to connect your QuickBooks account to Square to import transactions, you can do so using this guide in connecting QuickBooks Online to Square.
If you receive an error message when trying to connect Square with QuickBooks, I recommend that you contact the support team outside the Community. They will be able to do more troubleshooting steps with you to get the accounts connected as well as notify our engineers. You can join them with these methods:
Schedule a Callback or start a Chat: click (?)Help in the upper right > type and enter "Contact support" into the QB Assistant > click Contact Us > explain your situation > click Let's Talk > choose Get a callback or Start a Chat.
