Belastingadviseur gezocht voor particuliere IB-aangifte 2021 for myself, emplyment

Plaats: Eindhoven

Toelichting
I came to the Netherlands in 2019 and started working in July. According to the evaluation i am supposed to receive 1.5K back for that year. However, i think i filled in the form that was mailed to me wrongly. So, the final evaluation states that i will receive nothing back.

I need some help in rectifying this.
This declaration is for myself only. My income is from employment. I do not own a house.

Kind regards,
