Unfortunately, Charles Schwab Bank and Credit Cards are currently not supported.
As for specific community section for Bookkeeping discussions, I'll pass this along to our managers to take into consideration. In the meantime, you'll find the current Support Site for Bookkeeping users very useful for help topics and submitting any support issues with the plan.
Hope this helps out.
