Credits and deductions

I'm running into issues, too. When I input all the medical expenses I wanted to claim, I could see my return as $600, but when I added in the period for claiming the expenses (including a couple months in 2022), it dropped to $400. I continued on but later thought that maybe the issue was that by choosing a date in 2022, I was not able to claim the premium for those months because I would have claimed that for 2022. I thought I would go back and optimize the claim by changing the claim period, but the software won't allow me to do that.  The expert from Turbo tax tried everything to help me go back and edit the date range but couldn't do it and suggested I restart my tax return. Arggghh
