Lens might not be the problem

Text is sharp, if you take a picture of something else. Move the object to the center of the kitchen, and it might be sharper.

Also, might need more then 5x zoom.

Powerful flash. Set it to 1/16 and point it up. If you are standing up, it might be slightly to much.

How are you supposed to get everything in the frame in focus? The small text on the bleach isn’t in focus at all.

More pictures here, no flash is worse.
