I'm trying to submit my files but TurboTax block be saying my busines Economic Activity Code is not valid. I've tried about 30 of them, all coming from StatCan.

I've followed the indication here : https://turboimpot.intuit.ca/info/code-dactivite-economique-une-necessite-pour-les-declarants-travai... which led me to https://www23.statcan.gc.ca/imdb/p3VD_f.pl?Function=getVD&TVD=1181553

Which gave me tons of valid codes, all of them are rejected by TurboTax.
