Start at the beginning of the form and the first option to enter the 'Payer TIN" is under the checkbox for "if this is corrected', once you enter that number into proseries in that field (an error will most likely pop up saying the zipcode and/or address needs to be entered)  - it will flow down automatically and be entered into to that second Payer's Identification Number for you, and below that is where it is looking for the address information; once the complete address is entered, any errors should clear out. 

*Right clicking on the field - 'Cross Reference' is your best friend in ProSeries!
