Deductions & credits

I just got married in Sept 2019 and my rude awakening is that my refund as Married filing jointly (MFJ)  is about 80% lower than if Single still.

 

ny questions:

1. is for rental property I own renting at a  LOSS - TT says its no longer deductible. Does TT carry that over to when I sell my property and then I can apply the however many years of losses or is that $loss uh, lost forever?

 

2. also would it make sense to create an LLC and run my rental unit through that setup? More tax refund that way?  Thx in advance.
