Paper NJ State return

Hi,

 

I have filed my paper NJ State tax return on 3/20 and tracking still says 'in transit' after it departed the USPS Regional Facility Distribution Center in Trenton, NJ on 3/21.

 

Did it get lost or is it normal that it can take that long to be delivered to the NJ Tax Center?

 

I am starting to get worried

 

Thanks
