Based on the wings, and assuming this is no hybrid.... that is a baby alexandrine. Indian ringnecks DO NOT have red on the wings!
And... also based on feathering.... when you shared the photo, the chick was likely around 6 weeks old.... which should mean that the chick is now around 7 weeks old.
Looking at growth charts of the species you have can help to determine age!

Found a video series!
So you may be looking at another 5-7 weeks of feeding formula... but as the chick ages, he, or she, will be eating less and less baby food. That's normal.
I would highly recommend providing sprouted seeds and finely chopped fruits and vegetables. Maybe finely chopped walnuts, too? If you plan on feeding pellets, also offer those. It's okay if the baby doesn't eat the food, you still want to provide it as he/she may start exploring the food with their mouth.
If the chick is up for exploring at all, you can also offer safe foliage from trees. Providing different textures and items can help to "socialize" the chick to a variety of things. Using a vacuum, playing music, etc are all great things. Once the chick is old enough, safely taking the chick places can be great as well. This can work on teaching going into a carrier safely, *maybe* wearing a harness... going to the vets office, hardware stores, or other areas that animals are welcomed. (ensuring bird is ALWAYS secure) If you choose to keep this baby, it will make it easier if you ever need to go to the vets office or somewhere if your baby is already used to car rides, carriers, etc.
