Hate to break it to you, but this will never be fixed.

No matter how many replies to this post, no matter how many suggestions through Help.

I have been complaining and reporting this issue for years before this post started. 

The best you are going to get is the scripted replies from robots that monitor this forum. (They have to be robot replies because an actual human would recognize that their suggested solutions do not solve the problem.) 

They will NOT give an option to turn off auto-matching, for the same reason they will not fix it to match against the check number field instead of just the amount. 

The only logical conclusion is that Intuit has a reason for it to work this way. Most likely that it would cost more for programmers to fix than it costs to program bots or pay someone to copy/paste irrelevant solutions and make apologies. 

I had hoped the “new” Bank Feeds would fix this, but as with prior Bank Feed improvements, it’s one step forward and two leaps backwards.

It didn’t fix existing issues. It ignores existing rules created over years of use with no way to even print the old rules to help in recreating them. Plus the idiotic use of Shift+L and Shift+R (just try to Add More Details and enter a Customer or Vendor with a capital “L” or “R” and see what happens…). 

Intuit has no incentive to fix issues that don’t affect core functionality. They have had over 80% market share for as long as I can remember. None of the other options have even a tenth of that. 

Until that changes, they couldn’t care less about fixing an “inconvenience” that cost us time and costs them nothing.
