Retirement tax questions

Okay, I understand that, thank you. So my understanding before was that half of my wife's SS Disability benefits was not taxable, it appears that is incorrect. Also, I had thought that there was some kind of sliding scale where you would only be taxed on SS amounts up to 85%. So my take on what you are saying is that for the purpose of entering the SSA forms data in TT, I am going to simply enter the amounts from both or our forms as listed in Box 5 with no other considerations.
