I have noticed you played your last two games against Full Court Press defenses, they force turnovers, it's probably why you are asking for advices.
18 TO is quite acceptable against a FCP. 26 was maybe a tad too much but it looks like it was a crazy game, extremly high-paced, I am not sure you have lost the game on TO. I don't know if you need to focus on reducing turnovers but handling and passing are very nice to have at all five positions anyways.
All the advices you were given are good. Against a FCP, handling is important, the manual is very clear about it.
