Correct you have a 10 year ban for overstaying, pre 18 does not count.
 
So can you apply, yes, if they find that you are otherwise approvable they will need to submit a waiver application, a D3, which will add a bit of time. Obviously nothing is happening now with the the Consulates closed.

I believe since you have at least a year overstay after you turned 18, you would have a 10 year bar (I don’t believe time prior to turning 18 counts).  Therefore, it is up to you,  it if a 10 yr bar is in place, applying for a B2 seems a little pointless right now.
 
Good Luck!
