Same here!!

I talk to someone in the chat and they weren't very helpful. Your better off filling with another tax software that allows to enter all your slips separately.

Thanks for your advice, I was about to give up!

But I combined my two T4!

It corrected box C on relevé 1 so it didn't matter that I couldn't edit it.

I'm done 😅

Hi @tuna2015 
I would not be surprised if you worked for a School board. For some reasons, certain School board ("Centre de services" or formerly known as "Commissions scolaires") do that. 

@Genivi 's solution to combine both T4s together is the way to go!  Good call!  By doing so, your on-screen Relevé 1 (RL-1) will be pre-filled and will more than likely match the RL-1 you have on hand (unless an unlikely error was made by the issuer).  As @Genivi rightly pointed, Quebec Tax Withheld at source will require an entry, and other boxes as well (like Box J, if applicable).

So if the two T4s are combined and RL-1 is pre-fill expect box A, G and I. What should I do or I leave blank.

Hello @Oeniola3 

Great question. Don't leave them blank. Enter the necessary amount to match the RL-1 you have on hand.

Have a nice day!
