I just efiled federal

Do you have a specific question regarding your e-filed return that we can assist with?

I efiled both federal and State of Michigan.  I have a federal refund and owe the state. After successfully e-filing, I received no further instructions on what to print, mail etc. .

If you e-filed your returns, you should not need to mail anything in unless the program instructed you to do so.  Please see Do I need to mail anything after I've e-filed? for more information. 

For information about paying your state taxes, see What are my options for getting my state refund or for paying any state taxes I owe?
