Hi there, RTM2281.
Thanks for bringing your question forward here in the Community. I'd be glad to lend a hand regarding the company liabilities posting to the general ledger(s) in your QuickBooks Desktop account.
As you mentioned, the way to currently to get the amounts posted in the general ledgers for Social Security and Medicare expenses would be with the journal entries you're using. I can see how helpful it would be to have that process be done automatically. I'll do my part and pass your feedback along to the Product Development Team. Many product upgrades and features come directly from great user suggestions like yours. You can keep an eye out for these kinds of updates by viewing the QuickBooks Blog.
If you have any other questions, please don't hesitate to reach back out. I'll be here to help.
