Great Lessons you are an excellent teacher - my piano playing is growing leaps and bounds.

I recently downloaded your Boogie Woogie Lead Sheet (not sure from where) page 2 of the sheet bar 34 the bass notes are listed as

F, F, A, B, B#, C, F, C

My question is am I playing C twice since B# is enharmonically C?

What chord is this?

I have attached a screenshot of the bar I am asking about.

Thanks kindly for responding.
