A profit-sharing contribution is an employer contribution, not an employee contribution. It is therefore not includible on Form 8880. Only voluntary employee contributions (elective deferrals or contributions to a Designated Roth Account) or IRA contributions made by the individual are includible on Form 8880.
Since a profit-sharing plan is a qualified retirement plan established under section 401(a), distributions from a profit-sharing plan reduce the amount of employee contributions or IRA contributions considered for the Retirement Savings Contributions Credit and must be included on Form 8880 line 4 if made during the period beginning two years prior to the tax year and ending on the due date of your tax return that includes this Form 8880.
