Why am I getting 0 deductions for my rental property

Is your AGI over $150,000?

If your modified adjusted gross income (see the instructions for line 6, later) is $100,000 or less ($50,000 or less if married filing separately), your loss is deductible up to the amount of the maximum special allowance.

If your modified adjusted gross income is more than $100,000 ($50,000 if married filing separately) but less than $150,000 ($75,000 if married filing separately), your special allowance is limited to 50% of the difference between $150,000 ($75,000 if married filing separately) and your modified adjusted gross income.

Generally, if your modified adjusted gross income is $150,000 or more ($75,000 or more if married filing separately), there is no special allowance.

If 2021 is your first year renting out the property, then to add more possibilities to @ColeenD3 's response, use the below information to confirm beyond a doubt you entered things correctly.

Rental Property Dates & Numbers That Matter.

Date of Conversion - If this was your primary residence or 2^nd home before, then this date is the day AFTER you moved out, or the date you decided to lease the property – whichever is later.
In Service Date - This is the date a renter "could" have moved in. Usually, this date is the day you put the FOR RENT sign in the front yard.
Number of days Rented - the day count for this starts from the first day a renter was contracted to move in, and/or "could" have moved in. That would be your "in service" date or after if you were asked for that. Vacant periods between renters do not count for actual days rented. Please see IRS Publication927 page 17 at https://www.irs.gov/pub/irs-pdf/p527.pdf#en_US_2020_publink1000219175 Read the “Example” in the third column.
Days of Personal Use - This number will be a big fat ZERO. Read the screen. It's asking for the number of days you lived in the property AFTER you converted it to a rental. I seriously doubt (though it is possible) that you lived in the house (or space, if renting a part of your home) as your primary residence, 2nd home, or any other personal use reasons after you converted it to a rental.
Business Use Percentage. 100%. I'll put that in words so there's no doubt I didn't make a typo here. One Hundred Percent. After you converted this property or space to rental use, it was one hundred percent business use. What you used it for prior to the date of conversion doesn't count.
