Either look for the PDF file you should have saved when doing Mr. Cooper's 2016 tax return. If you did not save the return as a PDF, Install TurboTax 2016 on your computer and have TTax 2016 search for Mr. Cooper's 2016 return.
TurboTax 2017 can import 2016 tax file, but cannot let you see the actual 2016 return.
If this fails, you can still file the taxes by mail.
