Deductions & credits

I just had a chance to look at the title and original paperwork and it was JTWROS.

 

If I am understanding things thus far, technically my mother shouldn't have been issued a 1099-S as the sale of the house was both her primary (and only) residence for over 30 years, and below the $250,000 threshold.

 

But since she was issued one (with only half of the actual sale price listed), it may be in our better interest to simply file a state and federal return for the 1099-S.

 

Is my understanding correct?

 

Thanks!
