Business & farm

You have a pair of options.  One is do not check the box that you intend to get the payment in 2021. 

That will end the perpetuity nature of the payments and should end the Schedule C connection. 

The other option is to delete the Form 1099-MISC and enter the income as Less Common Income Income, Other Taxable Income.  

The first option is preferable; however the requirement is to report the income.  The income is taxable and not subject to self-employment tax.  Both options will achieve this objective.
