I use desktop which also doesn't allow viewing the calculation but i found a way that may work if you are using online
1)Open the return.
2)Go to the tab Other Tax Situations. Then down to Additional Tax payments. Then to the Under Penalty Payment line and select Start or Update
3)Continue until you reach the "Penalty Waiver" page and select yes
4)Continue to the "Request Waiver" page and select yes
5)Continue to the "Reduce Penalty" page and select Waive Part
6)Continue and for the amount waive you center a small amount like $10. for the explanation a single letter will work - continue and check "done with Penalties"
7) Now select File > Print or Preview (print if you what to either print it out or save it as a PDF)
😎 select Form and supporting statements under specific forms
9) in the forms list select only the Form 2210 penalty worksheet
10) click on print or preview depending on what you selected in 7
you should now see the Turbotax calculation worksheet
this worked in desktop. don't know about online
