Text box won’t format to one line

When I use the text feature, it will not allow me to format it to one line of text. If I select the text box, it brings up transform, which only changes the size (or skews/distorts it). I want all words on one line. It's not a space issue, because I can transform the text box to a tiny size. When I write just two words it does multiple lines. When I write a short sentence, it will divide the words up on different lines with no rhyme or reason. I don't want to use the premade text styles. I've searched online for an answer and it seems a lot of other people have the same problem with no solution. I'm not asking for fancy text edits; I just want to do basic text formatting!
