Congrats on making your first post here in the Community. I hope your day is going well so far.
If the "Missing transactions" that you're referring are duplicated or not needed in the account, then I recommend deleting the transactions. However, I do suggest consulting with your accountant to be sure. They'll be able to give you the best accounting advice for your business. If you don't have an accountant, you can cruise on over to this link to find one near you.
Here's how to delete (Exclude) the transactions:
Go to the Banking tab on the left-hand menu bar.
Select the Banking portion.
From the For reviewsection, locate the two transactions.
4. Put a check in the box beside them.
5. Press Exclude in the dark gray bar.
Afterward, you can find these items in the Excluded tab within the banking page. Furthermore, you can start reconciling your account when you're ready.
After talking to your accountant, you should have the best route for your business. If you run into any trouble along the way, just let me know. I want to ensure that you're able to get back to running your business. Have a great day!
