You will need to add a product with a price of $1 and then add a quantity selector with a text box, in the text box the users will enter the amount they want to donate. 

Here's a guide that will help you adding a quantity option: https://www.jotform.com/help/225-How-to-Add-Options-to-Payment-Forms 

I hope this helps.
