I am filling out the for the naturalisation application through settled status (5 year path). I have 3 questions

Q1:In my second year of university, I left the UK in March 2020 because of covid. However, the lease for student accommodation was until July 2020. I am asked for the last 5 years of my address Should I say I lived there until March 2020 or July 2020? I technically only lived there until March, but I also don't want to leave a huge gap.
Q2: Also, I have a 2 week gap in the middle of 2021 as I was sleeping at my ex's couch. Should I give her address (I wasnt registered anywhere), leave a gap or just say I lived at the previous place for 2 weeks longer?
Q3: I left the UK for 457 days in the last 5 years. I gave this reasoning at the end of the form (see pic below). Can I add anything else? Should I also answer the questions below? The last 3 questions look like theyre asking about the same thing (let me know if the image doesn't work)
Thank you very much
