"Accepted" only means the tax return is downloaded into their system. It sounds like Marylands system started accepting returns on 1/25/23 or 1/26/23.
"Processing" means examining the return, checking for errors, and deciding whether to pay a refund or hold for more information. Even in the best of times, processing takes 2-3 weeks. There may be delays at busy times, especially at the start of the season (when they have a backlog of fresh returns and they are just finding out if their internal processes updated for 2022 actually work) and around the April 15 deadline when there is another rush.
Then if a refund is released, it may take another week to show up in your bank account.
