Electronic filing of T4 summary

This is my first time using sage to file T4's electronically. I went through all the steps and an XML document was created, however as far as I can tell there was no T4 Summary created. Is this correct? My issue is, I did not have my remittances set up in sage for 2017 so my T4 summary is incorrect unless I am given an option to put an amount in the "other remittance" box. I can only do this however if I print to paper. Am I missing something? Is there another step for the summary when submitting electronically or does the summary have to be submitted on paper regardless or is a summary not required for an electronic submission?
