When I click the box to Maximize Contribution to Individual 401(k), TurboTax calculates this but does show the amount. How do I see this calculated value?

On screen to input contributions to Individual and Roth 401(k) Plans, there is a box to input Employer Matching (Profit Sharing) Contributions, and beneath this is the ability to check a box to have TurboTax Maximize Contribution to Individual 401(k).
