You can also always check pages like "Ebay Kleinanzeigen" by yourself (https://***.ebay-kleinanzeigen.de/s-wohnung-mieten/tuttlingen/c203l8503?gclid=CLKpwpGtts0CFc1uGwodqU0Idg) where people post their flats, or pages like "Immo Welt" (https://***.immowelt.de/liste/tuttlingen/wohnungen/mieten?lat=47.9827&lon=8.8141&sr=10&sv=1&roomi=2&rooma=2&Wflma=60&sort=relevanz%20distance). You just need to tipe in the amount of money you can spend and the amount of rooms you need.
I really hope you find something, but since you already have the approval of the jobcenter, I think it won't be that hard.
Let us know if you need any further help.
Best
Henriette
