Regarding the Premium Tax Credit - I had health insurance through Covered California for the first 4 months out of the tax year, and then once I got a job with benefits, I started recieving employer sponsored health insurance. However, even though I started recieving health insurance from my job in May, I didn't call to cancel Covered California because I assumed it would be automatically stopped. I contined to pay for Covered Cali up until August (I essentually had "double" health coverage up until then). When I recieved my 1095A, it was reflecting that I was recieving health coverage through them up until August. Therefore, it appeared that I had to pay them back even more for the discounted rates they were initially giving me. (Also keep in mind my income drastically went up when I became employed, so the amount I had to pay them back was over $2k). Even though I had a 1095-C (form showing I was recieving healthcare by my employer) to show my Tax preparer, she still had to go by what my 1095A form was showing, which signaled I was having cheap insurance provided by Covered Cali. Therefore, I got a substantiall chunk of money that was deducted from my refund ( money I had to pay back). How can this be mitigated in the future??

You were supposed to cancel the ACA healthcare instead of assuming it would be cancelled automatically somehow. This was your own fault. Sorry. You can try talking to healthcare.gov but there is nothing that TurboTax can do to help you mitigate the problem.
