Hi there @Ryan_M and @David-212915 thank you for your prompt response.
I guess what I'm trying to figure out is why the manual entry isn't showing up on the lists of matching transactions. As far as i know it should show up.
If we'll look at the first example below, this is what I manually entered on QB. This has not been previously reconciled or excluded.
And on the second image, the entry isn't showing on the lists. 
Am not sure why this is happening and it has been an ongoing issue. The amount of what I'm trying to match doesn't matter (at least for me) since i can override whatever is in excess of the amount to be reconciled.
Hope to hear from you soon.
Thank you.
Hi @girlie16,
Thank you for your reply, as well as the screenshots you provided.
Let's consider the images you provided as an example of what I mentioned earlier. Your recorded transaction amount is $152, while the downloaded transaction you're trying to match is $112.
As stated above, the screen where you can match recorded transactions will only show those with amounts that are equal to or lower than your downloaded transaction. This isn't an ongoing issue with the product, it's the normal operation of QuickBooks Online.
To put it to practice, you can edit the $152 transaction and split it into 2 parts. Say, one part is $112 and the other is $40. Retain the same transaction date to ensure they will appear. If you try to find a match for the $112, I'm sure you'll see the edited transaction on the list.
Don't hesitate to leave a comment below if you have other questions. I'll get back to you as soon as I can.
