No, it is not a problem. Enter your surname starting with the first letter and enter as many letters as the space will take. This will not affect your tax return in any way and it will not delay it. The IRS uses a specific pattern for identifying individuals with their name and social security number. It does not use all of the letters, however the beginning letters of your name are what matters.
