I’m self employed running a daycare, it just told me I can get a bigger refund if I add more write offs .. what can I add to make my refund bigger

Maybe a home office ?  Read up on your situation ...  

If you are new to being self employed, are not incorporated or in a partnership  and  are acting as your own bookkeeper and tax preparer you need to get educated ....  

If you have net self employment income of $400 or more you have to file a schedule C in your personal 1040 return for self employment business income. You may get a 1099-Misc for some of your income but you need to report all your income.  So you need to keep your own good records. Here is some reading material……

In particular, the use of your home, for providing day care services, is more generous than the "home office" rules for other self employed persons, working out of their home.

I highly recommend going to a tax professional that specializes in daycare and/or reading Tom Copeland's books (Google him).
