Im trying to add apple card to quicken for downloads i have put all login info and it will not work

You cannot currently sync Apple Card to Quicken like you can with other cards. The closest available option to that is to manually export the transactions and then export them into Quicken. See: Download or export your Apple Card statements and transactions - Apple Support

My wife and I have same issue. We got our Apple Cards, but soon we found out about these limitations. We are not using the cards anymore due to the simple facts that we can't connect them to our Quicken. Doing monthly exports might be good if you have 2-3 transactions to track, but it is ridiculous expectations when you use the cards daily and have 100+ transactions per month. I have no time to reconcile it on a monthly basis as I need to do it on a daily basis. Apple should offer the connection to Quicken. We will give them few more months and if no options, we will be canceling the cards as they are missing key feature that we need.
