Maryland Sales and Use tax question... How do you report sales that collected on platforms like Ebay?

I am familiar with submitting sales tax via t Maryland Connect website if all sales had sales tax I collected myself. I am not sure if I need to enter sales from Ebay anywhere else since ebay collects sales tax for the buyer's state.

-Do I report both Ebay and Non-Ebay local sales all together under Gross sales?

-Does Ebay sales get reported anywhere else, like under the "facilitator" section? Or do I just report all sales on the first line, and then only the sales that I collected sales tax myself on the line "sales subject to Maryland 6%"?

-I plan to contact my tax agent but not sure if I can get them now that it's the weekend. Thanks for any help!
