Too late now, but  who you mail a tax return you should use a mailing service that will track it like UPS or certified mail so you know the IRS got it.  

When you mail your tax return, wait about 4 weeks and then check the IRS site:  

To track your Federal refund:   

https://www.irs.gov/refunds

To track your state refund:

On the IRS site you are also offered the use of an app called IRS2Go
