Add additional payroll deductions on paystub

Just started with Sage 50, when paying employees, some of them have more deductions than the paystub will allow, so it wants to print on the next check.  I know there is an option to print on plain paper, which I haven't quite figured out yet, but we changed the layout of the paystub and shrunk the height of the fields so we could add more.  We copied and pasted on of the fields, and actually had room to add 4 more deductions.  Now it duplicated the field we copied, how do I change where it is getting its information from?  Thanks!!
