"How many TVs do you have at home?"
Translation:Kolik doma máte televizí?
"Kolik máte televizí doma." sounds odd (It is gramatically correct but nobody would say it) . Better is "Kolik televizí máte doma" or Kolik máte doma televizí."
"doma máte televizí kolik?" this is a correct translation. This variant emphasizes that for the questioner is most important the "number of tvs you have at home."
