Tax return

I am unable to figure my estimated return because the system wouldn’t allow me to input the loss from selling my company last year.  I do not have the money to pay up front to file taxes.  I am wondering if a tax pro can look at my taxes and see if there will be a refund and if there will be then file them and collect payment from the refund.  My accountant last year said there would be a refund but that was before I pulled 25k out of my children’s college accounts.
