Brothers. how and where do you declare your khums and Zekat on your IRS tax forms?

I have been giving both of  my Khums and Zekat as weekly  instalments every Saturday night  to a young Muslem sister with a little child and no husband and on a very low income. On top of that It takes me one hour drive from my house to hers each way. I think I should also claim milage.

My question is where do I declare this on my tax return form? Under charitable donations section of tax form  they want the name and address of charity with registration #. The sister refuses to register as a charity. She gets annoyed  shouting what do you think? Do you think it’s a f#####n  charity?

Brothers please help. I have only 4 days to complete this and my  Khums and Zekat contribution was huge this year
