Excel EOMONTH date function

Question

I am trying to use EOMONTH in excel, but I cannot make it work... It i not recognising my date as a date.

I am using excel for mac (ver16.45), in column I type for example 01.01.2020, or 01/01/2020 it always formats as 1.1.20. When I try to change formatting I have asterisk for default date as in my system as *14.3.12 and I leave it like that... than when I use =EOMONTH(C1,0)...

I am getting error ("Not trying to type a formula? When the first character is an equal ("=") or minus ("-") sign, Excel thinks it's a formula")

I know that for EOMONTH excel need to recognise data as a date, and that it needs to be in format of the system... but for me is simply not working...

I don't know is it mac maybe, or what can be...

Thanks!

It would be helpful if you could upload a copy of your workbook, or at least a screenshot of your scenario, so I can get a full understanding of your request. Based on your initial comment, can you replicate my screenshot and let me know if it works?
