How to grab earlier transaction history during account setup

A new user as of this morning, setting up my spending and cash accounts now. When I look at the individual accounts I've set up, the "Earliest Transaction Date" is different on each one. I'd ideally like to have transaction data beginning at least at 01/01/2020. QUESTION: How do I get Quicken to go back and grab earlier transactions on my accounts. :/ Long story, but if it matters, I won't be able to install "Quicken for Windows" on my laptop for a few months, so using Quicken on the Web exclusively until then.
