DS160 Intended Length of Stay, Passport expiry date or 797 expiry date?

In Ds160 , I gave 3 years as intended length of stay but while going over stmaping documents I came across a statement that said passport should be valid for atleast 6 months beyond intended length of stay.
My passport expires in one year. Should I just redo the whole DS 160 with new intended length of stay as 1 year instead? Has anyone faced this situation
