I'm missing a big chunk of transactions but when I tried to upload them as a file, it said that they already existed.

Hi Michelle,

You'll only get an error saying your transactions already existed when you re-upload them or when QBSE detects identical transactions. However, you can click Include all transactions to view the transactions you're trying to upload. From there, you'll be able to upload them.

Before you start, set your transaction filters to All first. Maybe the transactions are there but just hidden because of the filters.

Setting the filters to all:

Force import the transactions:

You can also check about categorizing transactions for your additional reference.

Let me know if you need more help with importing your transactions. Have a good one!
