W2 Box-12: Roth IRA Plan vs. SIMPLE IRA Plan

Hello all!

 

On my W2 under box-12 it has "S" and then the amount on the screenshot below. When continuing, this message pops up. The plan I contribute to is a SIMPLE IRA plan, not a Roth IRA plan. Does this mean I would put $0 in for contribution since I did not contribute to a Roth IRA? Or is this a system error and I should put the full amount? I feel like it's an error since a SIMPLE and Roth IRA are completely separate, I'm just not sure which one it's meaning to ask for. 

 

Any assistance is greatly appreciated!
