To be able to use deductions and write them off they all have to more than the Standard Deduction everyone gets. so if you don't have more than these amounts it's not worth even putting them in.

Single 6,300 + 1,550 for 65 and over
HOH 9,300 + 1,550 for 65 and over
Joint 12,600 + 1,250 for each 65 and over
Married filing Separate 6,300 + 1,250 for 65 and over
