Cannot adjust Self-Employed Paid Sick Leave Credit entry (form 7202)

I entered a dollar amount when I was asked in Turbotax Desktop Home and Business for this credit, but now I cannot go back and adjust it. I've attached a screenshot (with amounts blacked out). I navigated here by going to Personal/ Deductions and Credits/ Tax Relief related to COVID-19/ Self-employed Sick Leave Credit. I cannot click on the blue rounded square. Am I going to the wrong place? pdf.jpg
