Python naming conventions state that function names should be in snake case and one letter variable names are not acceptable. Also, there is no need for a self argument as the function isn't a class method:
def is_match(check_string: str, pattern: str) -> bool:

| dp = [[0 for i in range(len(p)+1)] for j in range(len(s)+1)] |

| if(p[j-1]==s[i-1] or p[j-1]=="."): |

The parentheses are unnecessary and redundant:
if p[j - 1] == s[i - 1] or p[j - 1] == ".":
...| if(p[j-1]==s[i-1] or p[j-1]=="."): | ||
| dp[i][j] = dp[i-1][j-1] | ||
|

| elif(j>1 and p[j-1]=="*"): |
