Knowing the size of a 20 gallons she/he looks big for a one year old ! Did you get it as a 1” baby ? Sure it's a girl if so you will end up needing a large tank once an adult. Looks older than one or just way overfeed. Growing too fast. How long is she now , the shell ? If unsure on sex any picture of front claws ?
Work on your basking area , has only one spot to fit on. Also lower it to just above the water level. It’s close to what looks like a screen lid and that bulb. Looks like a CFL/UVB in front fixture whats in the back fixture ? Turtles are much stronger than most think and could push it up to escape , unless it has clips on it. Maybe a larger floating dock with the bulb's on one end. Would give it more room so if she wants to just dry off without being directly the bulb. Would offer varying temp for her to choose. Let her decide what she wants. Also floating type does not take up good swimming room in a small tank which she will out grow soon. Or make an (ATBA) above the tank basking area to buy you some time before an upgrade is needed. More basking will get rid of that algae on her and help the shell too along with adjusting it’s diet.
