I've heard many conures who are a WHOLE lot noisier than my amazon lol. Conures seem to like to vocalize as loud as they can as often as they can. It takes a lot of work to get a parrot of any species trained for apartment living. They also need no-chew and potty training so they aren't messing up the apartment (we've been renters as long as we've had our bird, landlords appreciate quiet birds who don't crap on the carpet and chew up the baseboards and doors). A few helpful tips since you sound VERY new to parrots:
1. Don't cover her while your at work, unless you are working night shifts. She should have activities to do during the day, like toys to shred and foraging for treats to keep her occupied.
2. Get her on a schedule ASAP. Up at the same time every morning, to bed at the same time every night. Parrots NEED a solid 10 hours of sleep (and will still take naps in the day). They are lazy creatures of habit lol. But in all seriousness, it is VERY VERY VERY important for a bird to have a routine. She should know what time she is woke up, what time she is fed, what time you play with her, what time she spends alone while your at work, what time she gets her dinner, what time she plays with you after work and what time she goes to bed. It'll take a couple months, but I cannot emphasize enough the importance of a good routine for parrots in homes where they will be left during the day!
3. Ignore "bad" vocalizations and encourage "good" vocalizations. If you ignore her when she scream, but praise and reward her when she makes a cute noise or says a word (if she speaks) which one do you think she'll make more often? Be consistent. Again, it'll take a while, but she will get the picture that soft, cute noises get the attention and loud, ungodly squawking doesn't. Though, as a bird she will occasionally vocalize loudly and will likely flock call in the am and pm (short bursts of loud squawking).
4. Look up target training and start working with her ASAP. The better the bond you build early on, the easier it will be to train her as time passes. Target training is was and effective. I like "Michael Sahzin, The parrot wizard" personally, especially for beginners. He gives clear, concise and accurate instructions. He has lots of free videos on youtube. I suggest you look into him and other trainers too to see which one's style you connect with best so you can follow a program and get her trained to be an excellent companion bird.
Best of luck.
