you can have at least $12,200 in adjusted gross income without having to pay income taxes however you may have to pay self-employment taxes as follows. TT will compute these taxes from the entries you make on schedule C,
net income from schedule C times .9235 = taxable SE earnings. if the result is less than $400 you owe no SE taxes. ignore the following. if $400 or more multiply the result by .153
if all this is bewildering to you, you may want to upgrade to have a TT pro prepare your return or you can pay for a pro. I don't know what your financial situation is, but if either option is unaffordable you may want to contact your state's CPA society. if you qualify they may prepare your return for a lower charge.
