revised 1099r

After I filed my return I received a "corrected" 1099R (although the corrected box was not checked).

 

The "correction" was the inclusion in box 16.. State Distribution of the amount that was missing when the first 1099R was produced/sent.

 

No state tax was withheld in either case and the distribution code (7) remained the same.

 

Do I need to file an amended returns?
