Address issue in Ds 160 form

[dsnaveen]

Hello,
Iam applying tourist visa for USA.
I have filed the DS-160 form,submitted and interview also scheduled, in 1 section it says
Address where you will stay in US
I have give NA.

If officer ask her in interview, why i gave NA in address, should i mention, my travel plan was not fixed, hence i gave NA..
OR
should i carry a new DS-160 form while going for interview, and tell mistake in address
any suggestions please let me know
Thanks,
