I've been dealing with this issue for 2 years, spent countless hours, and with Quicken support and they cannot help (so far). So, for the last two years I have been entering my Schwab transactions manually, reconciling myself, etc. without being able to download from Schwab into Quicken.
I know the problem and the solution, but I cannot figure out how to implement "the solution" in Quicken. The bottom line is whenever I authorize quicken to connect to Schwab, it downloads and messes with GOBS of history, and it royally screws up everything. Account balances all wrong, categorization missing and/or screw up, etc.
I've done this and restarted with a fresh back up numerous times and can't get it to stop. The solution is to get it connected to Schwab but do NOT download and/or sync/touch ANY of my Quicken history. I have that all done and up to date. I just want it to start downloading stuff going forward. I cannot get it to stop doing that and support is no help. They just keep telling me to do the same things I've tried 20+ times.
I even created a whole new quicken file, connect to schwab, downloaded and accepted everything, then went back to my correct file to no avail. I am using Windows 11 and have been using Quicken since 1993 and have had Schwab the entire time. It's a nightmare. I just need to know how to connect to Schwab while telling it not to touch anything in Quicken. And yes, i do have the "auto entry" stuff all off, etc.
