Submitting Multiple Documents (W2s and 1099s) When E-filing CD/Download on MAC

I'm wondering how to submit W2s and a W2c as well as 1099s  with federal and state returns. I am working on Turbo Tax CD/Download, and when I initially tried to import a W2, it wouldn't take it so I submitted all the information for W2s, W2c, and the 1099 forms manually.

 

I need to submit several documents digitally if I plan to e-file (and this seems like a requirement in MI, with few exceptions).

 

I found links on this topic, but most were for the online Turbotax version.

 

The one I found for CD/Download (https://ttlc.intuit.com/turbotax-support/en-us/help-article/import-export-data-files/import-enter-w-...) did not help me figure this out.

 

Please advise.

 

Thanks
