CatinaT1,
Thanks again for your response with details. I actually spoke with my insurance company and they asked me to ask to my local tax advisor even though they are the ones sent me this form. It actually makes sense to me because Insurance companies shouldn't decide taxable amount but IRS.
According to IRS, it is clear that It is the taxpayer's responsibility to determine the amount to be taxed in this case. It is the first time for me to receive this form and new concept to me where you put the amount by yourself and have the supporting documents backed up if anything come up later.
