On April 2018, I moved from Alberta to Quebec. I received Two T4 and Two identical Releve 1 with each T4 by mail from DND. The first T4 is for working in Alberta and the second T4 is for working in Quebec. I am Military so my employer hasn't changed. Both my T4 was entered into turbo tax by downloading it from CRA website but the software did not enter any data for the Releve 1 for each T4.
At the beginning of the Profile Section of your return;
Online users - The first question asked - Did you work in 2018? Yes - Check - I was employed - Check - T4 - Check - I worked in Québec and received a Relevé 1 slip
For those using the downloaded version, the first question you answer about "working" will open the dropdown and you will see the option to check RL-1.
If needed see below:
What do I do if I have a T4 slip with no matching RL-1 slip or an RL-1 slip with no matching T4? - https://bit.ly/2Smoqmn
I am in the same situation as OP. I am military currently living in Quebec and have a T4 from NB and QC, and a single releve 1 for the QC T4. I filled out the T4 from QC with its corresponding releve 1, but I am unable to fill in the T4 from NB without a releve 1. I get an error msg stating that my values for B and B1 on the releve 1 dont match with lines 16 and 17 of the T4 (obviously since I put all values as zero on the releve 1 tab for the NB T4).
*The only way I have made it work is by filling in values for the releve 1 to match the T4 from NB, though that is essentially creating a releve 1 that doesnt exist...?
