I did not claim my medical plan premiums for 2019 on my 2019 tax return. Can I claim them on my 2020 tax return?

Yes, you can claim any eligible medical expenses if they occurred in a 12-month period that ends in the current tax year. After you enter your medical expenses, TurboTax will prompt you to choose your 12-month claim period. So if most of your expenses occurred later in the year for example after April 2, 2019, you can use a 12-month period of April 2, 2019, to April 1, 2020, and claim all expenses that fall within that period. Keep in mind that you cannot claim any expenses that fall before your 12-month claim period.
