Did somebody successfully submit a tax return ONLINE if you haven't worked the whole year (UNTERJÄHRIGE tax declaration)?

We moved to Switzerland last year and we need to submit a tax declaration for those few months we have worked last year. I tried to submit it online on Zürich website but the website throws an error that unterjährige tax declarations can’t be submitted online. Does that mean I have to print it and send it by post?

I found out that quick login version with the access code doesn’t work, you have to make a full account on ZH Services portal and then it works.
