Depending on where you generated the file, it might be a carriage return, a linefeed or a CR+LF. You can use a text editor such as TextPad that can show binary characters to open the file and see what the end of line character(s) is. Once you find that, do something like shown below. Here I am using tab as the field separator and LF as the row separator. (I am going to the extreme here using dynamic SQL, you probably wouldn't need to do that, but this should work. Just be careful about sql injection if you end up using dynamic sql.
DECLARE @filename NVARCHAR(128) = '\\yourdomain\yourshare\yourfolder\yourcolbofile.txt';
DECLARE @sql NVARCHAR(4000) = '
+ @filename +
FIELDTERMINATOR = ' + CHAR(9) + -- tab
', ROWTERMINATOR = ''' + CHAR(10) + '''
