Welcome back to the Wefugees community and thank you for reaching out to us again.
Are you currently living in the Landkreis Meißen? If I am not mistaken, the updated regulations say that you have to submit the Umverteilungsantrag at the immigration office of your “destination” municipality - the place you want to live in future.
I found this form you could use, for instance. I think the application itself is not requiring one specific form - this might depend on the respective immigration office (Ausländerbehörde) though.
I hope this helps and please don’t hesitate to get back to us with any further questions.
All the best,
