Basement odor in upstairs A/C vents

I can smell basement odor coming out of my upstairs A/C vents.

I am renting a condo for the summer. The basement floor has had recent floor sanitizing which has an odor. I can smell this odor coming out of upstairs vents when my A/C is on.

I closed all outflow vents and return vent in the basement.

What am I overlooking? Can I expect to not have basement air mixed in with my upstairs A/C?
