Lost old Steuererklärung - can it be retreived

So my compute died some time ago and 2021 tax declaration pdf copy appears to be the only year whose tax form copy was only on the computer and not on drive or elsewhere...

As the tax office must have the submitted document (it was filled in online) does it make sense to ask them for a copy? Anyone had a similar situation?

It does not only make sense, but it is super easy https://www.zh.ch/de/steuern-finanze…bestellen.html

The link seems to be for the tax bills. I will try my chances nevertheless. Thanks

edit: it is indeed possible to request the entire form when filling in the form given
