Investors & landlords

I should also note that I received the proceeds from the sale directly at closing, and they withheld Maryland income tax since I do not live in the state.  I'm hoping that I can file MD taxes and get those funds back?

 

Lastly, my mom sold their primary residence in Jan 2021 with the same split (25%, 25%, 50%).  I assume that I would file this the same way?

 

I also have to file her income taxes, so any help is greatly appreciated!
