If you don't know which subcategory, then that requires someone hunt through all of them for you.
However, I find a note that you submitted it to Business/Investing/Stocks_and_Bonds/Equities/Research_and_Analysis
and you submitted to Business/Financial_Services/Investment_Services -- where an editor moved it to Business/Investing/Research_and_Analysis
An editor will decide which if any category is appropriate.
You may have submitted to other categories, but I'm not checking for them. Please note that ODP asks you to submit to one category only.
