TurboTax says I need to enter my employer's QST account #, but my employer is in Ontario and doesn't have one. I wfh in Quebec. Should I not claim the QST rebate?

My employer doesn't have a QST account number because they're based in Ontario, but I work from home in Quebec and have work expenses to claim. TurboTax shows me an error and insists I enter the QST account number, on the TP-64.3-V form "provided by my employer" (that they don't have because they're an Ontario-based company). What should I do?
