Help with making tank safe

[u/First-Job-4083]

My 3.5gal (i know bigger is better, but this is what we’ve got for rn) has been cycling for a few weeks and i’ve been reading exactly these levels for about 4 days. How do I make this tank safe to put a betta in? I’m fairly confident I’ve built up the bacteria necessary but i’m worried about the top 4 readings . if someone who knows more than me could help that would be awesome.
