require clarification regarding my account and the bank account

[Jack...@hotmail.com]

For many years I have kept a Quicken account called Rent1, and
reconciled it by hand with the bank's records called 8600...
This year I started downloading account 8600 from the bank, and I
stopped reconciling.
The downloaded items appear in a separate window below my regular
Rent1 register. When I "accept" a line item , ideally, the cursor
finds a matching item in my register, and I can enter details.

I am getting the impression that I should do this downloading and
accepting, before hand entering that same check or deposit in Rent1. I
think I'm getting cases of double entry. My balance is all wrong.
My intention was that the bank 8600 downloaded items were there just
simply to help me and save me from reconciling and not to take up
equal space in the register, alongside of the original Rent1 which I
have had for 15 years.
when I run a report on a property, I have become aware that I can pick
Rent1 or 8600 or both. The side window has 5 accounts and all have red
flags next to them and there doesn't seem to be any option force
selecting in that window. in customizing the report, of course you can
specify which accounts and I'm not sure whether I should include them
both or favor one over the other.
I would really appreciate it if someone could give me some guidelines
for operating these two accounts.
Or should I try to rename my Rent1 to have the same name as the 8600?
I can no longer print reliable reports. John P.
