Can I claim expenses and loss for inherited property without income

My mother passed away in the last quarter of 2020 and left me a rental property in her will. She had received all rent for the year 2020 and her 2020 taxes have been filed and accepted by irs. I had some expenses during 2020 for the property after I inherited it but no income for it for 2020.  I have not filed my 2020 taxes yet and have an extension. Can I file Schedule 1 and Schedule E to claim my expenses and show a loss for the property?  I will show a profit or gain for 2021.
