1099-MISC Incorrect from Rental Property Manager; Company not correcting

Hello, I have attempted over the past two months to address an incorrect 1099-MISC with my property manager for my rental properties, to no avail. With only days left until taxes are due, I am done with this person. I have the necessary documentation (year-end statements; ledgers) proving that their 1099-MISC is wrong. The question is, how do I properly report this in Turbotax? From what I have read, I need to submit supporting documentation with my return.

 

First question is: How do you submit supporting documentation with your return in Turbotax?

 

Second question: Do I change the 1099-MISC value to the correct value?

 

Thanks, in advance!
