Manual transaction Question for a newbie

kell75

I'm new and just getting set up with Quicken. I downloaded my account info from my bank, which is awesome. However, I like to schedule my payments online for during the month on the specific vendor pay portals. Obviously these won't show on my checking register until they hit my account.

I know I can manually enter these transactions for the date they will pay. However, does Quicken know when it downloads the transactions later in the month that I already entered it manually? Or will I have to look out and delete any duplicate transactions?

Thank you!
