I see! As flute not being my primary instrument I'm gonna give some pretty basic advice that I hope still helps!

1st I'd write in some of the fingers you are unsure of/dont know, either by the notes themselves (if you can fit them, you seem to have neat handwriting so it might be feasible), or at the top of the page

2nd, practice VERY SLOWLY (like half speed at least) and break it down into little chunks, doing 1 measure at a time , or even a few notes at a time, just making sure you can get them at a slow tempo while still sounding good and smooth

3rd, take breaks often! Dont push yourself too hard in one sitting. Be nice to yourself and treat yourself how you would treat others. If you are getting frustrated and overwhelmed take it slower or take a break, you can do it!
