Solution 1: No payments have been made to the vendor since the vendor was designated a 1099 vendor.
Only payments made to the vendor after the vendor is set up as a 1099 vendor will be tracked for the 1099 statement.
If you set up a vendor as a 1099 vendor in the middle of the payroll year, for instance -- 1099 statements are based on the payroll (calendar) year -- any payments made to the vendor before you set up the vendor as a 1099 vendor won't appear.
To manually calculate the amount, you can use the Vendor payments report. Customize the report for the period in the calendar year previous to the date you set up the vendor as a 1099 vendor. Then add that amount to the 1099 statement. (To enter or change 1099 income amounts)
Solution 2: 1099 statement amounts are based on the current payroll year entered for the company file.
Check the payroll year displayed in the General Payroll Information window. If the year displayed isn't the year for which you want to print the 1099 statements, you must change the payroll year to the current year. To change the payroll year, perform the Start a New Payroll Year process. (Closing a payroll year and starting a new one)
