Return for study

Good afternoon!
I have a question regarding tuition tax refund. In 2015, I paid for a year of a master's program in Holland (about 7 euros) and I know that within 000 years you can get the tax deduction refunded. The payment was made from my Dutch account, but the money was previously transferred to it by my parents. In 5, I worked for only 2015 months and already received a return for that year, given the fact that I almost did not work that year. A couple of months ago, I resubmitted my declaration for 2 indicating the tuition fees, to which I received a letter from the tax office with the text:
Uw aanslag inkomstenbelasting / premie volksverzekeringen 2015, is the door de inspecteur opnieuw berekend. De verschuldigde inkomstenbelasting / premie volksverzekeringen is niet gewijzigd. Het verzamelinkomen is opnieuw vastgesteld. Ter informatie zijn, indien van toepassing, ook de verliesstanden en de stand van de persoonsgebonden aftrek opgenomen.
Does it make sense to file an appeal and try to return something, or because I worked for only 2 months, nothing will be returned?
Thank you!
Best regards,
Anna
