10(13A)

I have received HRA & it is in pay slip, but it is not mentioned in FORM 16 by my employer by mistake.

now I want claim in filling ITR 1, under sec 10(13A),

I already read the 80GG , it is saying that person who do not receive HRA can claim under 80 GG, But I received HRA.

pls tell me claiming under 10 (13A) as exemption is correct ???
