I net filed my own return and it never asked for my husbands income information. I tried finding the log in for return manager and I couldn't find it.

If you already NETFILED your income tax return and would like to include your spouse's income, you will need to file an adjustment request.  Please see the following FAQ for instructions on how to submit an adjustment request.
