No, you should not enter the code differently. You must select code 2, the code that is actually your Form 1099-R.
There is no difference between the handling of code 2 and code 7 on your tax return. If any of the distributions being reported with code 2 were actually made after you reached age 59½, contact the payer and have them correct your date of birth in the account records so that future distributions will be reported with code 7.
